In plotly.js, how may I get call a javascript callback called when a slider is changed,

[pdenapo]

I have found an answer in

Trigger Slider event

I am using the basic slider example to show my scatterplots with time slider. Is there a way to capture the events on slider change ? I would like to call my APIs and do some other operations (not related to plotly chart). Have seen solutions adding new trace, but my problem is much simpler that I need to call my function on slider change event. Regards, Rizwan

It is very tricky. The documentation should provide an example of this common task. If you have many slidders, you should
set a name property for each and check its name as in this code

function handleSliderChange(e) {
let sliderName=e.slider.name
let stepLabel = e.step.label
if (sliderName==‘a’)
{
console.log(“a=”,stepLabel)
}
else if (sliderName==‘b’)
{
console.log(“b=”,stepLabel)
}
}
